How to clear cookies of the Unreal webbrowser?

[anonymous_user_45a80c78]

Hi,
I’m trying to use the webbrowser to create a login for facebook/google.
However the cookies of this browser are not cleared after every session.
This is how I create my browser

	FBrowserContextSettings browserContextSettings("myID");
	browserContextSettings.bIgnoreCertificateErrors = true;
	browserContextSettings.bPersistSessionCookies = false;
	browserContextSettings.CookieStorageLocation = ServerEnvironment.BrowserCacheLocation;
	FCreateBrowserWindowSettings webBrowserSettings;
	webBrowserSettings.bUseTransparency = false;
	webBrowserSettings.Context = browserContextSettings;

	TSharedPtr<IWebBrowserWindow>  browserSP = IWebBrowserModule::Get().GetSingleton()->CreateBrowserWindow(webBrowserSettings);
	TSharedPtr<SWebBrowser> browserWidget;
	browserWidget = SAssignNew(browserWidget, SWebBrowser, browserSP)
		.ViewportSize(FVector2D(GEngine->GameViewport->Viewport->GetSizeXY()))
		.ShowControls(false)
		.ShowAddressBar(false)
		.OnUrlChanged(BIND_UOBJECT_DELEGATE(FOnTextChanged, OnBrowserUrlChanged));

	GEngine->GameViewport->AddViewportWidgetContent(browserWidget.ToSharedRef());

After I’m done I try to clear my cookies like this:

TSharedPtr<IWebBrowserCookieManager> cookieMan = IWebBrowserModule::Get().GetSingleton()->GetCookieManager();
		cookieMan->DeleteCookies("", "");

In the IWebBrowserCookieManager.h it says:

Removes all matching cookies. Leave both URL and CookieName blank to delete the entire cookie database.
The actual deletion will be scheduled on the browser IO thread, so the operation may not have completed when the function returns.

Why are my cookies not cleared? Is this a bug?

Any help would be appreciated.

This worked for me

        
IWebBrowserSingleton* WebBrowserSingleton = IWebBrowserModule::Get().GetSingleton();
if (WebBrowserSingleton)
{
  TSharedPtr<IWebBrowserCookieManager> CookieManager = WebBrowserSingleton->GetCookieManager();
   if (CookieManager.IsValid())
   {
    CookieManager->DeleteCookies();
   }
}

Note in DeleteCookies() also says

The actual deletion will be scheduled on the browser IO thread, so the operation may not have completed when the function returns.

So you may need some bind or delay before restart your browser.

I tried this on UE 5.1. It does not seem to work unfortunately. Another user here used the same code above. It did not work as well.
